KAXE Staff Phenologist John Latimer provides his weekly assessment of nature in Northern Minnesota. This is the week of Oct. 15, 2024.

This week has brought dropping temperatures, bare branches, and flocks of migratory birds to the Grand Rapids area.

This fall has been a late one, with trees staying green and full of leaves past their seasonal averages. Many folks hope that this means it will be a mild winter and an early spring. John referred to his records to check this prediction’s accuracy.

The latest fall in John’s records was in 2013, when red maples reached peak color on Oct. 11. (John’s 40-year average for this event is Sept. 21.) With such a late fall, folks were hopeful that the winter would be short and mild – however, that was not the case. The spring of 2014 was one of the latest on record. John concluded, “The fact that our red maples weren’t at peak until the end of [September] this year means absolutely nothing concerning the coming winter.”

"So, all I can say is: buckle up and enjoy it. Get out there and make use of all of that wonderful winter that is in front of us, and it includes a lot of great activities that I enjoy. I’m sure most of you who are listening probably have some things that you like to do in the winter as well: Cross-country skiing, snowshoeing, skating, ice boating, it doesn’t matter. There’s just a million things to do – just walk around and look at the birch seeds laying on top of the snow. It’ll all happen at its own pace.”
